Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thread go / no-go gauges, in particular to a thread go / no-go gauge for testing. Background Art
[0002] The inspection of threaded holes includes whether the thread tolerance is qualified. Usually, a thread go and no-go gauge is used. When one end of the go gauge can be smoothly screwed into the screw hole and the other end of the no-go gauge cannot be screwed in, it means that the screw hole is qualified. However, the existing thread go and no-go gauge has no external protective structure. When in use, due to improper use, the thread go and no-go gauge is directly placed on the workpiece table, resulting in wear or rolling impact, which will cause the thread go and no-go gauge to fail. Since it is a measuring tool, it needs to be sent to a designated measurement unit for repair, which is troublesome and costly. Utility Model Content

[0006] Preferably, a hexagonal sliding hole having the same cross-sectional shape as the go / no-go gauge handle is provided at the tail end of the outer sleeve, so that the outer sleeve can slide back and forth on the go / no-go gauge handle. An inner hole groove is provided in the go / no-go gauge handle, and a spring is embedded in the inner hole groove to push the outer sleeve forward.
[0007] Preferably, a push plate is fixed by screws at the tail end of the outer sleeve, and the push plate is fixed by the screws after crossing the inner hole groove, so that it is convenient for the outer sleeve to be installed on the through-end thread gauge and the stop-end thread gauge are threadedly connected to the two ends of the through-end thread gauge and the stop-end thread gauge, and the outer sleeve is put into place before the through-end thread gauge or the stop-end thread gauge is threadedly connected.
[0008] Preferably, a soft silicone lining is fixedly provided on the inner side wall of the outer sheath, and the soft silicone lining effectively improves the protection of the thread threads of the stop-end thread gauge and the through-end thread gauge.
[0009] Preferably, an outer buffer sleeve is sleeved on the outer ring of the outer sleeve, and the outer buffer sleeve is made of rubber.
[0010] Preferably, energy-absorbing and buffering deformation holes are provided at annular intervals on the outer buffer sleeve. After being impacted, the energy-absorbing and buffering deformation holes can quickly absorb the impact energy by deformation, thereby effectively reducing the impact on the outer sleeve, and further reducing the impact on the through-end thread gauge and the stop-end thread gauge.
[0011] The advantages and positive effects of the utility model are:
[0012] The through-end thread gauge and the stop-end thread gauge are effectively protected by the outer sheath. When in use, the outer sheath is manually pulled back to expose the through-end thread gauge or the stop-end thread gauge for use. After use, the outer sheath automatically resets for protection, which makes it convenient for users to place it at hand, effectively improving safety and enhancing convenience for users.
